1,172,293, Original application filed January 16,

Fort Wayne, in the county of Allen and State of Indiana, have invented certain new' and useful improvements in Combined Valves and Pipe-Couplings, of which the -following is a specification.

The invention relates to a combined valve and pipe coupling adapted particularly tor use in connecting a branch pipe with a main line pipe, and is shown in my application Serial No. 677,995, tiled Jan. 16, 1912, ot which application the present application is a division, as constituting a part ci the connections used for supplying lubricating maf terial 'to the bearings of an engine or similar machine.

rilhe invention is particularly adapted for use inl connecting branch lines o" relatively thin copper or other ductile material, to

`main line pipes termed ot the same material,

and which piping is of such a character that it Will not readily admitA of threading connections thereinto, as, tor example, copper tubing, Which is very desirable for use in forming lubricating oil connections. 1t will be apparent, however, that the invention. is

applicable to any condition in which it is.

desired to connect branch pipes to main line pipes ot the described character, and it is therefore not desired to be limited to use in engine oil connections or titings.

In the drawings, constituting a part oi' this specification, Figure 1 is a cross-sectional 'view through a main line pipe to Which is attached my combined valve and pipe coupling, the principal parts of the device being shown in section. Fig. 2 is a side elevation of the device of Fig. 1. Fig. 3 is a view in section through the casing on line 3-3 of Fig. 1, looking in the direction indicated by the arrows. y Fig. 4 is a broken sectional view on line Ll-i ot Fig` 2 showing the preferred construction of the casing of the coupling and means for attaching same'to the main line pipe. Fig. 5 is a view similar to Fig. 4, showing a modification oi the construction of the coupling and particularly the means for securing the same to the main line pipe.

A main line pipeordinarily used :as conduit for iiuids such as lubricating oil, and the like, is indicated by the reference char- Specicat'ion of Letters Patent.

acter 10. This pipe may be o'rined of 'copper or other suitabie rnatin'iale preferably o'f'a ductile nature.

The reference character' 11 designates an opening through the relatively` thin Walls of the pipe or tube 10, theimaterial of which may not be of sufficient thickness-to permit ot the secure fastening of a 5lconnection thereto by threading the Walls around the opening 11.

The reference character 12 designates a branch line tube or pipe which may also be termed et" copper or other suitable ductile material, so that the walls ofthe tube will be relatively thin; and in .order to torni a -duid-tight connection between the interior ot' the tubing 12 and the interior of the main line pipe 10, and the vent 'or opening 11 therein, li provide the coupling casing indicated generally by lthe reference character 13. 'the casing 13 .is preferably a casting of suitable metal which may be machined, and is provided on its interior with an'opening 13a preferably somewhat largerl than the exterior diameter ot the main line pipe 10 which it is adapted ,tofsurround in order to torni a connection between the vent 11 of the main line pipe and the branch line 12. At each extremity of the casing 13 and the hollow interior 13 thereof the Walls ofthe casing 13 are slightly contracted, as indicated at 13b (see Fig. e). ln order to attach the coupling to the main line pipe 10 after the vent oraopening 11 is tapped therein, the casing13 Will be placed in position over the pipe 10 with the opening 13 leadin to the valve seat 13d in position for rea y communication with the opening 11 in pipe 10. The reference character 13e designates a branch chamber or opening in the casing 13 commuicating with the opening or passage- Way 13, communication between the two latter interior portions of the tting being under the controlot the valve 14 carried at the lower extremity of valve stem 15 which latter has an enlarged threaded collar in engagement with a corresponding threaded portion ot' casing 13 at the upper extremity of the chamber or passage 13e, by Which the rotation of valve stem 15, by means of a suitable hand Wheel or other operating device 16 at the upper eXtremitv thereof, will cause the valve 1a to engage tne seat 13d, or to be lifted from the seat, thereby establishing or closing communication between chamber 13c and the opening 135 at will.

r[he reference character 17 designates a gland nut threaded into the walls of the upper extremity of the casing 13'and provided with an opening for the valve stem 15 whereby the operation ot' this nut will place any desired degree oi' pressure upon packing member 18 thereby forming a iiuidtight connection between the upper extrem- -ity,oi the casing and the valve stem' 15.

The packing 18 may be retained in position against downward thrust by means oi' a washer 19 shown in Fig. 1, or any other suitablc means. The material of the casing '13 surrounding the outer extremity of the chamber 13e. is reduced in the form of a nipple. and threaded exteriorly to take thel interiorly threaded connecting nut or collar 20. This is a common connection or coupling and the outer extremity of the threaded collar or coupling 20 is reduced beyond the threaded portion to correspond with the exterior diameter of the copper tubing 12 the inner extremity of which is bellmoutlied as indicated at 12a, so that when the collar 2O is tightened upon the exteriorly threaded portion of the casing 13, the bell-mouthed portion 12a will he clamped tightly between the casing and the collar 20, and a Huid-tight joint or coupling formed between the parts. IVhen the casing 13 has been placed in position over the main line pipe 1f), with the passage 13c in communication with the vent 11, and the pipe 12 has been connected with the casing 13 by the tightening of the collar 20, the connec- --tion between the main line pipe 10 and the slightly enlarged to permit of the entry of a` considerable body of soldering material and thereby expedite the forming of a fluid-tight joint at the ends of the casing around the pipe 10.

In Fig. 5 I show another means of closing the extremities of the casing 13 ar'ound pipe 10, which consists in the use of the threaded collars 22 of wedge shape in cross section. and coperating with the threaded interior extremities of casing 13, whereby the tightenlng of the collars 22 will exert a wedging actionbetween the casing and the pipe,

thereby rendering the interior 13a of the casing, liquid-tight with respect to the casing and pipe 10.-

I claim:

1, A pipe fitting comprising a body hav- 'ing an integral pipe encirclin sleeve and a 'passage extending through t e body and 3. In combination, a pipe having a lateral opening therein; a fitting encircling said .pipe and covering said opening, said fitting having a passage extending around and separated from the pipe with one end registering with theopening in the pipe and its other end opening radially and outwardly from the pipe; and means sealing the jointV between said pipe and said fitting.

4. In combination, a' pipe having an opening in its side; a fitting encircling the pipe and covering said opening,Lthere being a passage through said fitting having one end registering with the opening in said pipe,

extending radially a short distance from said opening then turning at a sharp angle and extending around the pipe for substantially 90Owith its other end directed outwardly away fbm the pipe; a valve in said passage at the sharp angle thereof adapted to control the flow of fiuid through the passage; and means sealing the joint between the pipe and fitting.

5. A pipe fitting comprising a body having an integral sleeve portion adapted to encircle a pipe, there being a passage leading from the interior of the sleeve through the body; and means for connecting a branch pipe to the body in communication with said passage.

In testimony whereof I have signed my name to' this specification, in the presence of two subscribing witnesses, on this :27th day of May, A. D. 1915.
